Immunotherapy in Treating Human Cancer

The immune system of our body is a complex network of tissues, cells, and organs that act mutually to protect our body from unknown foreign trespassers. It recognizes the harmful particles entering the body and facilitates the destruction of those particles in order to shield the body system from any ailment. Due to any complexity or disturbance often the immune system targets the wrong particle considering it as a dangerous particle and this anomaly of the immune system may result in various autoimmune diseases like arthritis, allergies, malignancies, and AIDS (Understanding the ...

Abstract

Over thirty years after its identification, HIV and AIDS remains a somewhat elusive virus, particularly when it comes to its history as a human infectious agent, and resourcing a complete epidemiology of the disease. Part of the problem is that so many antiretroviral drugs have come out and have either been used or prescribed incorrectly. In addition, the virus, like many other reverse RNA transcriptase viruses, has a very high aptitude in terms of developing resistance to drugs at a very rapid rate. What further complicates matters is how quickly it has spread. It will probably never truly be ...

INTRODUCTION

In the 1980s a new disease was spreading. It was previously unknown, but seemed quite contagious and quite virulent. HIV, the Human Immunodeficiency Virus, is defined exactly as it sounds. It is a virus that causes an infection that negatively affects the immune system. That infection attacks and weakens the immune system, making an individual at greater risk for contracting other opportunistic diseases. When the immune system becomes too damaged it leaves the patient open to contracting AIDS, the Acquired Immunodeficiency Syndrome, which essentially disables the immune system, which leaves sufferers to deal with many of unpleasant symptoms associated ...

Human immunodeficiency virus (HIV) is a medical condition that can never be completely healed, as the virus will remain in the organism despite treatment. Furthermore, HIV can lead to acquired immunodeficiency syndrome (AIDS), which is the most advanced phase of HIV infection (Eramova, Matic & Munz, 2007). This chronic disease reached its peak in the mid-eighties, when an AIDS epidemic spread across United State and many other nations, causing the death of many individuals carrying this virus (Centers of Disease Control and Prevention, 2016). The virus continues to spread, increasing the number of people living with AIDS, which reached up ...

The reaction by a person being told they have HIV is often and very understandably very negative. Most people, even in the most undereducated countries in the world, understand very well that HIV is a life-shortening disease. Depending on a multitude of physical, mental, and socio-economic factors, living with HIV can be a horrendous damnation in which the person is shamed and shunned for the remainder of their life, or it can be another chronic illness among a list of others. In the United States and the United Kingdom, most people today who are the most susceptible consider HIV ...

Human Immune Deficiency HIV is the virus that causes AIDS- Acquired Immune Deficiency. The virus is spread through contact with the mucous membranes and the semi epidermal cells with infected bodily fluids such as semen, vaginal fluids, breast milk (Aids.gov). In Britain the most prevalent method of HIV transmission is through having unprotected sexual intercourse, the sharing needles is also another cause of HIV infections (Avert.org). Mother to child transmissions are rare, especially in the cases where the pregnant ladies attend prenatal clinics since HIV screening is mandatory. It is not spread through regular contact with infected people, swimming ...

Immunology

The rearrangement of T cell receptor (TCR) genes g and d occur in series of cells expressing variable Vg and Vd gene segments. The lymphoid precursor cells originate in the bone marrow and move to the thymus. Preliminary T cells are devoid of TCR, CD4 and CD8 molecules and are called double negative thymocytes . These double negative T cells may be further categorized into four phases of differentiation (DN1, CD44+CD25-; DN2, CD44+CD25+; DN3, CD44-CD25+; and DN4, CD44-CD25-) . CD44 is a cell adhesion molecule and CD25 serves as the IL-2 receptor. Passage into the DN2 and DN4 stages ...

December 1, is World’s AIDS Day. At the initiative of the World Health Organization, for the first time, this date was marked as World AIDS Day on December 1, 1988.
